Explore your data schema with Flux

Flux provides functions that let you explore the structure and schema of your data stored in InfluxDB.

Functions in the schema package are not supported in the Flux REPL.

List buckets

Use buckets() to list buckets in your organization.

buckets()

List measurements

Use schema.measurements() to list measurements in a bucket. By default, this function returns results from the last 30 days.

import "influxdata/influxdb/schema"

schema.measurements(bucket: "example-bucket")

View example schema.measurements() output

List field keys

Use schema.fieldKeys to list field keys in a bucket. By default, this function returns results from the last 30 days.

import "influxdata/influxdb/schema"

schema.fieldKeys(bucket: "example-bucket")

View example schema.fieldKeys() output

List fields in a measurement

Use schema.measurementFieldKeys to list field keys in a measurement. By default, this function returns results from the last 30 days.

import "influxdata/influxdb/schema"

schema.measurementFieldKeys(
    bucket: "example-bucket",
    measurement: "example-measurement",
)

List tag keys

Use schema.tagKeys() to list tag keys in a bucket. By default, this function returns results from the last 30 days.

import "influxdata/influxdb/schema"

schema.tagKeys(bucket: "example-bucket")

    measurement: "example-measurement",
)

List tag values

Use schema.tagValues() to list tag values for a given tag in a bucket. By default, this function returns results from the last 30 days.

import "influxdata/influxdb/schema"

schema.tagValues(bucket: "example-bucket", tag: "example-tag")

New in InfluxDB 3.5

Key enhancements in InfluxDB 3.5 and the InfluxDB 3 Explorer 1.3.

See the Blog Post

InfluxDB 3.5 is now available for both Core and Enterprise, introducing custom plugin repository support, enhanced operational visibility with queryable CLI parameters and manual node management, stronger security controls, and general performance improvements.

InfluxDB 3 Explorer 1.3 brings powerful new capabilities including Dashboards (beta) for saving and organizing your favorite queries, and cache querying for instant access to Last Value and Distinct Value caches—making Explorer a more comprehensive workspace for time series monitoring and analysis.

For more information, check out:

InfluxDB Docker latest tag changing to InfluxDB 3 Core

On November 3, 2025, the latest tag for InfluxDB Docker images will point to InfluxDB 3 Core. To avoid unexpected upgrades, use specific version tags in your Docker deployments.

If using Docker to install and run InfluxDB, the latest tag will point to InfluxDB 3 Core. To avoid unexpected upgrades, use specific version tags in your Docker deployments. For example, if using Docker to run InfluxDB v2, replace the latest version tag with a specific version tag in your Docker pull command–for example:

docker pull influxdb:2
